if you can do the following bit :

1. Clean the installation disk with liquid soap and gently clean it
(i'm not sure if this will really help but there is no harm in trying
this).

2. Ensure that you dis-assemble the computer once, clean all the
components, devices properly and then try it.

3. Using any other computer - Create a copy of your original windows xp
cd and while doing it, replace the file with the one you downloaded
from the internet. (try this only if the above two fail).
